I don't think many try to breed them because they are high effort low reward in my opinion. You'll probably need to mess a bit with your water because they need really soft water to spawn. The fry need really small food like infusoria before they get big enough for brine shrimp and other foods. I'm not trying to discourage you, but it might be a good idea to experiment with easier ones like congos or black neons first to build up experience. Wish you the best of luck
